An electric motor with microprogrammed controller and dual-functioning brushless commutation/rectification circuitry contained entirely within a wheel. The principal use of this electric motor is intended to be, but not limited to, powering a four-wheel drive electric vehicle through normal driving modes and serving as a power-recovery generator during braking. The magnetic and electronic configuration is optimized within the wheel to provide high torque and efficiency without the use of gear reductions, chain or belt drives, transmission, rotating axles, differentials, universal joints, or brushes. Power losses from mechanical drive system couplings are thus eliminated. Except for the wheel and bearings, there are no moving parts. Also, the wheel is virtually free of devices that are subject to mechanical failure.
